Designing confounders: Other demographics

- [Instructor] Onto Chapter 2, section 7,…where we proceed to designing demographic confounders.…So, this lecture will show you…how to design variables for ethnicity, race,…and other demographics.…The way the variables come in in the BRFSS,…and in most data sets,…are not suitable for analysis.…You'll understand why as I walk you through this.…This is why you have to almost always redesign…each variable you want to use.…Let's look at how I did this in the data dictionary.…

And back at our dictionary,…we can see that our smoking grouping variable…and the smoking indicator variable is documented.…Next on the list, we have two,…what you call two-state flags,…because they can only be 1 and 0,…and that is _HISPANC and SEX.…But as you can see, I redid those variables too.…Please notice that for some reason…they did not include the second I in Hispanic…in the variable.…So, I call it Hispanc!…I don't know who names these variables.…But you get to name your own when you design them.…

So, as you can see here on the Hispanc tab,…

Analyze behavior and risk using R, the open-source statistical computing software. R provides an environment and a language you can use to analyze data, including the publicly available Behavioral Risk Factor Surveillance Survey (BRFSS) dataset. This course teaches core healthcare data science skills, including epidemiology, as well as how to perform a cross-sectional analysis, set up a data dictionary, develop metadata, determine confounders, apply exclusions, create diagrams, generate continuous and categorical outcome variables, and more. Join biotech expert and epidemiologist Monika Wahi as she first discusses design and ethical considerations, and then takes you through the steps of conducting a descriptive analysis.

This detailed, practical course is designed to help those in the field of public health, medicine, and data science to edit, analyze, and interpret data. Learn how to code new variables, use the forward-stepwise modeling process, and document your decisions. Find out how to visualize results by generating charts and graphics, and how to add tables and figures to your documentation. This course helps equip you to independently design, develop, and execute a full BRFSS analysis, and even publish your results in scientific publications or journals.
